| Abstract: | The small satellite attitude control system, using three reaction wheels as control devices, is a nonlinear system with coupling. In this paper, a decoupling variablestructure control law is given, which directly designs four quaternion sliding surfaces instead of three ones in order to avoid calculating singularity. Simulation result of large-angle maneuvers shows that the law has excellent control precision and robussness, and is easily realized. |
